Answer: Correct answer is C -I just took the test
we have the function f(x) = 4(1/2)x, and we want to reflex it over the x-axis.
you can see in the graph that the reflex over this axis changes the sign of f(x) in all the points (where f(0) = 4, g(0) = -4, f(1) = 2, g(1) = -2, and so on), then the reflex, g(x) is equal to -f(x)
now we have:
g(x) = -f(x) = - 4(1/2)x
then the right answer is the third option:
g(x) = -4(1/2)x
Step-by-step explanation:
Answer: y - 7 = 1/2 ( x - 2 )
I hope you got a good grade on your assignment!! ^w^
Answer:
d. Both I and II are false
Step-by-step explanation:
When there is a high degree of linear correlation between the predictors the errors are found.
The basic objective of the regression model is to separate the dependent and independent variables. So if the variables have high degree of linear correlation then the multi collinearity causes problems or has errors. It is not necessary that multi collinearity must be present with high degree of linear correlation.
For example we have 3 variable of heat length and time. And all of them have a high degree of correlation. With increase in heat and time the length increases . But for multi collinearity with the increase of time and decrease of heat length does not increase. So this causes errors.
y-hat = 135 + 6x + errors
The linear relationship between height and weight is inexact. The deterministic relation in such cases is then modified to allow the inexact relationship between variables and a non deterministic or probabilistic model is obtained which has error which are unknown random errors.
y- hat= a + bXi + ei (i=1,2,3...)
ei are the unknown random errors.
<u><em>So both statements are false.</em></u>

The answer is 18.
I hope this helps :D
Answer:
THE answer is y= -2x²+16x-24
Step-by-step explanation:
OK, so the standard form for an equation is ax²+bx+c
When you look at the equation we see that there is a -2 all by itself so we need too bring it within the parenthesis, so we'll distribute it..... so now instead of 2(x-6), we have -2x-12..........Why? because (2 times x is 2x and 2 times six is 12)
next when you write it ALL out, you get (-2x+12)(x-2) now we need to put this in the standard form by using the FOIL method
F- first O-outer I-inner L-last..... so multiplying the First from both equations we get -2x², Outer is -2x times -2 which is 4 because two negatives make a positive, Inner is 12 times x which is 12x, Last is 12 times -2 whchis -24. Put them all together and you get. 2x²+12x+4x- 24, now we combine like terms (in bold) and we get -2x²+16x-24. Look at the standard form i gave above and see how the final answer matches
-2x²+16x-24
ax² +bx + c
